Product Service Systems (PSS) have been hailed as one of the most effective tools for transforming society into a resource-efficient, circular economy and sparking a much-needed "resource revolution" since the 1990s. This article examines the literature on PSS during the past ten years and compares the results to those of a previous review published in this journal in 2006. Nearly 300 articles were found to be relevant, with over 140 of them being cited in this study. PSS research has grown more prolific, with the number of refereed articles published quadrupling since 2000, despite the fact that overall scientific production has only doubled. PSS has also spread to a broader variety of scientific disciplines (such as manufacturing, information technology, business management, and design) and geographic locations (Asia currently generates more papers than Europe). The literature of the past seven years has improved insights into PSS design, as well as their economic and environmental advantages, and has verified definitions and PSS ideas that were accessible in 2006. Research into how firms have implemented PSS in their organizations, as well as the key success factors and issues that require special attention (such as a focus on product availability for clients; an emphasis on diversity in terms of services provided rather than product range; and the need for staff to possess both knowledge of the reasons for the lack of widespread adoption of PSS, especially in the B2C environment, seem to have been well addressed in the literature accessible in 2006. One of the most desired qualities for consumers is having control over objects, artifacts, and life itself. PSS are often less accessible or have less intangible value than competing products, in part because they typically do not offer customers with as much behavioral flexibility or even give them the idea that the PSS provider may dictate how they should act.
